All Notes (12)
Glider landed and stayed still for several days. RV Gould was gracious enough to lend time to recover. Words are coming in slow, wing loss, chipped digifin, and bottom scratches. Not sure which wing at this point.
Recovered by Chance Miller aboard RV Gould.
Switched to calling RU Analog
Glider is in long term drift mode calling TWR.
Given the tests the top culprits are the following in most likely order:
* attitude sensor is no longer reliable for heading measurements
* digifin is broken and stuck to one side
* combination of attitude, broken wing, unknown drag
Only remaining items to try are
* resetting the vehicle
* toggling power to attitude sensor
* surface sanity checks
* resetting power to digifin
* trying steeper angles (tried most of the shallow angles)
Glider is also suffering from a weak battery pack or running off a single pack that's also a tad weak. The compass started off working and from a slightly apparent possible wing loss event (roll change indicator, NOT ballast) it started acting strangely.
Shallow pitch angles did not change behavior. 30 deg down pitch still had issues.
Set fin in both directions, glider still apparently spun to right (at least thats what compass said)
Appears to have compass problems, turning around. C_science_on 0 turned off science to save power.
Downcast only optics.
u_alt_min_depth 80: false hits around 20-60 m
Box waypoint list, need to set -1 initial after it hits first waypoint.
Payload bay configured with BBFL2SLO-338 and BB3SLK-796
This glider also has the Aquadopp-P 24336 ; Head ID: AQP 4965; Hardware ID: AQD 9709 on board.
Deployed by Nicole and Filipa out of Palmer Sta.
After pump diaphragm leak in Antarctica fore steam was sent to Webb on 4/30/2010 for repair.
